ios 64 bit warnings #430

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
compile for ios 64 bit.
there are casting warnings.

In scale_neon64.cc

// TODO(Yang Zhang): Investigate less load instructions for
// the x/dx stepping
#define LOAD1_DATA32_LANE(vn, n)                               \
    "lsr        %5, %3, #16                    \n"             \
    "add        %6, %1, %5, lsl #2             \n"             \
    "add        %3, %3, %4                     \n"             \
    MEMACCESS(6)                                               \
    "ld1        {"#vn".s}["#n"], [%6]          \n"

%6 and %1 are 64 bit pointers, but %5 and %3 are 32 bit int's.
I think %5 (tmp) should be made into int64.
Can this line:
lsr        %5, %3, #16 

widen from %3 32 bit to %5 64 bit?

disassembly shows 64 bit registers (eg x0) are used for int.  e.g. most 
functions use int width for loop counter.

To avoid the casting warnings for ios 64bit, I think we can widen %2, %3, %4 
from 32 bit to 64 bit. I will try to fix it.
